WINDOW FRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 523,591, dated July 24,1894.

Application led February 26, 1894. Serial No. 501,588. (No model.)

- To all whom t may concern:

Be it known that I, ANDREW P. N1ELsEN,a citizen of the United States,and a resident of Richmond Hill, Long Island, in the county of 5 Queensand State of New York,haveinvented certain new and useful Improvementsin Window Frames and Sashes; and I do hereby declare that the followingis a full, clear, and exact description of the invention, which will en-Io able others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, which form apart of this specification, and in which- Figure l is a front view ofthe lower part of an upper, and the upper part of a lower, window-sashof my improved construction, with the adjacent portions of t-he casing;the facing or housing of the same having been 2o removed to show themechanism for raising and lowering the sashes. Fig. 2 is a transversesectional view on the horizontal plane indicated by the broken linemarked ocax in Fig. 1, looking downwardly; the dotted lines z 5indicating the position of the inside windowframe and sashes when swungopen; and Fig. 3 is a similar view on the same section line; butshowing, in dotted lines, the position of the sashes when swung openinwardly, with- 3o out also opening the inside sash-frame.

Like letters of reference designate corre sponding parts in all thefigures. I

This invention relates to the construction of window frames and sashesof that type in 3 5 which the sliding sashes may be swung open inwardly,when desired, to facilitate cleansing and polishing of the window-panes;and it consists in the improved construction of the compound or duplexframe or casing and 4o the sliding sashes, and in the combination of thesliding and laterally hinged sashes with the duplex frame; substantiallyas lwill be hereinafter more fully described and claimed.

On the accompanying drawings, the reference-letters A A designate thetwo parallel side-pieces or stiles of the stationary windowcasing; theupper sliding sash-frame being shown at B, and the lower sash at C,while the window-panes, framed in these sashes,

5o are shown at B and C respectivelyA Fastened by hinges CZ to one ofthe stationary stiles or side-pieces A is another frameDD, upon one ofthe sides, D, of which the vertical sash-guides or rails E and E arefastened, while the opposite side D is similarly provided with theparallel sash-guides F and F. The sash-guides E and E', appertaining tothe side-piece D are rounded off on the sides facing the slidingsash-rails B and C, as shownat e and e', respectively; and thesash-guide 6o F appert-aining to the opposite side-piece D', andcorresponding to the guide-rail E of the left side-piece D, is hinged,by a flap-hingef, upon the part D,so that it may be opened and swung toone side, out of the way of the window-sashes, as shown in dotted linesin Fig. 3.

The stationary side-piece A on one side of the window casing (in thepresent instance, the left side) is recessed longitudinally, as 7o shownat a a, to make room for the customary sliding sash-balances orcounterpoises G G (one for each sash), the cords Hof which run overgrooved sheaves I, and through longitudinal recesses h h in the adjacentsides of the sliding sashes B and C; the lower end of each sash-cordbeing fastened to its appropriate sash by one or more nails or screwsh', in the usual, well-known way. I use sashweights on one side of thesashes only, how- 8o ever, and employ in lieu thereof on the oppositeside ofthe casing two spring-actuated cog-wheels, J J, one for eachsash, which mesh with toothedracks, K K, fastened upon the contiguoussides of the sliding sashes. The Wheels J J are hollow and provided withinside springs, the tension or powervof which corresponds to the liftingpower of their appropriate weights G, connected to the 'other oropposite side of their respective sashes, so go that each sash will bebalanced by and between a weight, G, on one side, and one of thespring-actuated cog-wheels J on the other side. To make room for thecog-wheels JJ, the adjacent stationary side-piece A on that side of thecasing is recessed, opposite to the wheels, as shown at a a.

Upon the hinged (in this instance left) side of the movable frameDD, thesliding sashes B and G are provided, each, with a metal roe plate L, therearwardly projecting end of which is curved inwardly, as shown at Z, toform a bent tongue or bearing which will fit within a Vertical recess min the vertical sashguides E and E', back of and parallel to the roundedbearings e and e', which face and impinge upon plates L and upon whichthe sashes swing laterally in opening them inwardly into the positionillustrated in dotted lines in Fig. 3. To permit the sashes B and C,with their glass panes B and C', to be swung into this position, forcleansing and polishing, or for repairs, dac., it is necessary first toopen and swing back, out of the way, the hinged guide-rail F on theopposite (right) side, and remove the inner parallel guide-rail F bywithdrawing it from the groove or recessf' in the side-piece D' intowhich it is inserted. This arrangement permits of the opening, inwardly,of either` one of the two sashes, B or C, without disturbing the other,as they are hinged and work independently of one another, so that onemay be kept shut `While the other is opened inside the room forpolishing, and vice-Versa.

When it is desired to swing open both sashes at the same time, and withthem the hinged inner frame D D in which they slide, this may be done asrepresented in dotted lines in Fig. 2; frame D D swinging open,inwardly, upon its hinges cl d, and carrying with it the exterior broadguide-rails or facing-rails A' A', one on each side, as well as thesash-weight G G, with their appropriate sheaves and sashcords, and thebalance wheels J J, as clearly represented in dotted lines in Fig. 2.When in the closed position, Shown in full line, the hinged frame D D islocked to the stationary casing A A by hooks, or any other desired formof fastening not shown which can be easily and conveniently operated;and in order to permit the balance cog-wheels J J to swing clear of thestationary side-piece D', the two recesses o.' a are made in one,without any dividing wall between them.

By this construction, l am enabled to cleanse and polish not only thewindow panes, but the sashes, as well as the frame in which these slide,without endangering life and limb by making it necessary to clean orrepair' the windows from the outside of the building.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- The combination of the stationarywindowcasing A A recessed at a and ct'; hinged inside frame D D'provided with the Vertical facing-rails A' A', curved and recessed guiderails E and E', intermediate removable guiderail F and inner hinged railF'; sliding sashes B and C hinged independently to the guiderails E andE', respectively, by curved bearings or hinge-plates L Z;-sashweights GG and co-operating balance-wheelsJ J; all constructed and combined tooperate substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

ANDREW P. NIELSEN.
